How do I add the token expiry(lifetime) claim in Prosody (JWT Auth)

I have configured JWT token as shown below:

    authentication = "token";
    app_id = "example_app_id";           
    app_secret = "example_app_secret";    								   
    allow_empty_token = false;  

How do I add the exp and value to this, say, 1 hour expiry?

You set exp when you generate the token. Prosody is not generating tokens, only verifying them.

Yeah I figured, thanks
